TRANSMISSION. i

Application led May 27,

suitably arranged and mounted as to produce a simple and eiiicient transmission, which is not likely to require repair or replacement of parts for long periods of time.

Another object of my invention is to provide a vtransmission as above indicated, which is of light construction, efficient in operation, and v which may be constructed at a minimum cost.

lvfy invention will best be understood by reference to the accompanying drawings forming la part of this specification and in which Figure 1 is a top view partly in cross-y section of a transmission incorporating my invention; Y

Figure 2 is a cross-sectional view taken on approximately the line 2-2 of Figure 1 and, v

Figure 3 is a cross-sectional view taken on approximately the line 3-3 of Figure 1.

ln the drawings and for the purpose of illustration I have shown the preferred embodiment of my invention and in which numeral 5 designates a suitable frame member on which cross members 6 `may be secured, by bolts or set screws 7 thus forming a suitable frame work on which I mount my improved transmission. Numeral 8 designates the main drive shaft which may be attached to the automobile engine or other source of motive power. The shaft passes through and is rotatably mounted in a bearing 9 and f' surrounded by a coil spring'lO, which contacts against the inner end of the bearing 9 and a shoulder 11 of a friction pinion 12, which is composed of two steel flanges or side members 13 and 1li, anda central fric tion pov 'ion 15 made of rubber or other suit able friction material. The several parts of ysaid pinion 12v are secured rigidly together by means of bolts or set screws 1o,v and the 19:27. serial No. 194,707,

pinion is slidably mounted on a squared section 17 of the shaft 8, but is secured from rotation relative thereto.

Pinion 12 as shownin Figure 1 is in enn gagement with two similar discs 18 land is adapted to rotate the same in opposite di-y rections when the shaft 8 is rotated. Each disc 18 is loosely mounted on a flange 19 which is integral with the shaft 20; saidl flange 19 vis rigidly secured to a disc 21 by suitable threaded bolts or pins V22. Near 'the cuter edge of the disc 21 are pins 23 threaded on one end and securely screwed into the disc V21 and passing through disc 18 so that disc l18 is secured against rotation relative to disc 21, butzis adapted to yield away from disc 21 by compressing the springs 2d, which are mounted on the pins 23 and held in contact with disc 18 by nuts 25 on the outer end of pins 23.

Near the end ofshaft 18 is a beveled por- Y tion 26 and asmall cylindrical portion 2'? extending therefrom and] fitting into a cylindrical opening 28 in the squared portion 29 of shaft 30 and adapted for rotatoryj motion relative thereto. Shaft 30 vis the fpower. transmitting moans by which `power is transmittedto the drive wheels of the car and it is rotatablymounted in a bearing 31. Bearings 9 and 31 are secured to the 'frame pieces 5 by bolts 32 in any suitable manner. On the squared portion 29 of shaft 30 slidably mounted a friction wheel 33 which is normally in contact with discs 21 and adapted to be rotated by said discs, and it in turn rotates the shaft 30. Vheel 33 is coinposed of two steel side members 34 and 35 with a friction member 36 ofrubber or other suitable material, clamped therebetween by bolts or set screws 3'? in the same manner that pinion 12 is constructed.

In the side member 35 of wheel 33, is pro` vided a groove 38 in which is mounted a U- shaped collar 39 adapted to slide in said groove when thewheel' is rotated, and is loosely secured yto ka shift lever 40, by set screw-fs Ll1 attached to said collar, and adapted to slide in the slot l12 in the fork end of the shift lever e0. Near the uppercnd of said shift lever it is pivotally mounted on a I cross shaft 43, secured in suitable depending The enf incanta Vsaid driving disk adapted to engage said into engagement with said friction pinion,"
